Style WH Rod Wipers
Designed for medium duty applications and can provide both wiping and sealing action in one
component in low pressure systems. The external lip scrapes foreign matters from the rod, and
the other lips act as an effective pressure seal in low pressure applications. This wiper can also
be used as a secondary seal to trap slight leakage from the primary seal. This creates a very
dry rod system. APG stocks WH Rod Wipers in 90 Durometer Urethane, 90 Durometer Fluoroelastomer
and 90 Durometer Nitrile. In Fluoroelastomer and Nitrile, the WH Rod Wiper is also
known as Series 8600.
